# Lesson Plan: Area of Triangles and Parallelograms

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the area of triangles and parallelograms.

#### Objectives

Students will be able to

• calculate the area of a triangle using its base length and perpendicular height,
• calculate the area of a parallelogram using its base length and perpendicular height,
• calculate the area of a triangle or parallelogram in a real-life context,
• find unknown lengths in triangles and parallelograms, given their areas.

#### Prerequisites

Students should already be familiar with

• calculating the area of squares and rectangles,
• the units for measuring area,
• adding, subtracting, multiplying, and dividing whole numbers within 1,000.

#### Exclusions

Students will not cover

• areas of circles or sectors,
• areas of composite shapes,
• areas of shapes with noninteger lengths.
